The CoreWind SBC-SAM9G45 Single Board Computer is a high-performance controller board. It features a CM-SAM9G45 processor card which integrates an AT91SAM9G45 microcontroller, 128MByte DDR2 SDRAM, 256MByte Nand Flash, 4MB Dataflash, 2Kbit EEPROM, UART, Ethernet, USB Host, LCD, Touch screen, and RTC on board. It is connected with to the SBC-SAM9G45 main board through two 100-pin B-T-B expansion interfaces.

The board comes with the Linux 2.6.30 operating system with complete basic drivers which enable a quick means to evaluate the Atmel AT91SAM9G45 processor and customize application software. It would be an ideal development platform for multimedia and communication applications. It measures 158 × 141 mm and operates in the industrial temperature range -40°C to +85°C.

In addition to the interfaces provided on board, all other interface functions of the microcontroller are brought out to header pins organized by port or function, allowing for easy addition of peripheral modules.
